This is the iconic titular song by Gene Kelly (1912-1996). During filming, it was said that Kelly had a fever of 103 degrees Fahrenheit on the day of the filming of this scene and refused to take a sick day which would have significantly affected production schedules. From the film, this is one of the most intense choreographed moments in cinematic history with its intricate dancing technique executed by Gene Kelly, who was already a professional dancer and choreographer.
